The idea is she comes as a tourist, for which she would gain entry easily. Then she finds a job, gets the paperwork done and stays. (There's a lot of paperwork, so it won't be easy) We are also exploring the option of a student stay (no idea if that's feasible). In any case, after staying a year she can apply to become a Permanent Resident, and after two years as Permanent Resident she can apply to become a Citizen. Once she is a Citizen she can divorce, and the Phils have no say in it anymore. She can probably divorce earlier, but the Phils IIRC don't accept divorces that are not done by foreign nationals.
The whole workaround would take at least 4-5 years, probably longer, but at least we could stay together.
